Big Data

Big Data simply refers to a large volume of the varied amount of data. Here the varied amount of data means that the data may be structured or unstructured. This data is extremely important to organizations as it can be used to get valuable insights and help them to take better strategic decisions. There are a number of topics in big data for thesis and research but before that let us discuss the basics of big data.

Three Vs of Big Data

Big Data can be described in terms of three Vs which are:

  • Volume – It defines the amount of data produced from different sources such as social media, business transactions.

  • Velocity – It refers to the rate at which the data is produced.

  • Variety – It refers to different formats of data produced which may be structured, semi-structured, or unstructured.

Value and variety are the two new Vs that have evolved in big data in the recent times.

Hot Topics in Big Data

Hadoop

Since the amount of data produced is huge, an open-source distributed processing framework is designed to manage that data which is known as Hadoop. This framework helps in processing, storing, and managing the big data. It was developed under Apache Software Foundation and was thus known as Apache Hadoop. The Big Data Hadoop architecture consists of the following components:

  • Hadoop Common – Java libraries and utilities
  • Hadoop Yarn – For job scheduling
  •  Hadoop Distributed File System – For high throughput
  • Hadoop MapReduce – For parallel processing

Big Data Hadoop

The concept of Hadoop has already been discussed earlier that it is an open-source framework for processing and managing big data. It is a good area to look for good thesis topics in big data. A single Hadoop cluster has a single master node and multiple slave nodes. Hadoop File System(HDFS) is used for distributed processing and storage of data. It also provides high aggregate bandwidth across the cluster. The importance of the Hadoop lies in the fact that more than half of the data produced is unstructured. This technology is required to optimize that data properly. Following are the advantages of Hadoop:

  • Can process and store huge amount of data
  • High computing power
  • Fault tolerance ability
  • Low-cost framework
  • Flexibility and scalability

MapReduce

MapReduce is an algorithm for processing huge amount of data. This algorithm has two tasks to perform – Map and Reduce. In Map task, a set of data is taken and converted into another form by breaking down it into tuples. In the Reduce task, the output of the Map i.e. tuples is taken and combined together to form small tuples. The Reduce job follows the Map job. It is also a good field for research and thesis under Big Data. Two primitives mappers and reducers are used in the MapReduce model. The mapper processes the input data while the reducer process the data from the mapper. The MapReduce Model has the following main components:

  • JobTracker
  • TaskTracker
  • JobHistory Server

Big Data Tools

Tools are used to analyze and process the data.  Like Apache Hadoop, there are various other big data tools to manage data which is so large that it even exceeds terabytes in size. The big data tools are categorized on the basis of storage and processing. You can pick up a tool and start your research in that. Following are the top tools used in Big Data Analytics:

  • Apache Hadoop
  • NoSQL
  • Hive
  • Sqoop
  • PolyBase
  • Presto
  • Cloudera
  • Apache Storm
  • Apache Samoa
  • MongoDB

Big Data Analytics is expected to see a fourfold increase in the near future and these tools are going to help the companies for processing and analyzing the data. It depends upon the company regarding which tool to use for their business.

Big Data with R

It is one of the hot topics in Big Data for thesis and research. R is a programming language which acts as an interface to software developed in languages like C, C++, and FORTRAN. It is the language for data exploration and development. R and Hadoop can be integrated together in the following ways:

  • RHIPE

  • ORCH
  • HadoopStreaming
  • Hadoop Streaming

To manage big data with R following strategies are utilized:

  • Sampling – This strategy is used to reduce the data which is too big to handle
  • Use of bigger hardware – Bigger hardware helps in cases when the data gets large
  • Storing objects on hard disc – Instead of storing data in memory, it can be stored on hard disc and can be analyzed set wise.
  • Integrating languages like C++ and Java – It is another good strategy to increase the efficiency.

Big Data Security

No doubt big data is one of the emerging technologies, there are also security concerns of this technology. Big Data security is a term used to represent all the measures, practices, and tools used to protect the data from malicious attacks or thefts. It is an interesting area for research and thesis in big data. The threat can be either online or offline. To protect the data it is best to implement big data security. The main security concerns in big data include corrupting of the incoming data, threat of stored data being stolen, third part attack. Encryption technique is used to protect the data from these security problems. Firewall is another useful big data security tool that can filter the traffic.

Big Data Analytics

Big Data Analytics is a hot research area under big data. It is a strategy to analyze large volumes of data collected from a number of resources such as social networks, digital media, transactions etc. The main aim of data analytics is to identify different data patterns from large datasets.
